Would it make sense to split this patch into two parts? One general "add i.MX6 SoloLite support" and then the "add mx6slevk board board support"?

I haven't looked into the manual, but are these the clock registers? If so, is it necessary to set them to 0xffffffff? Or are these already the default reset values?
